COLLAPSIBLE BABY-CARRIAGE.

Application filed Ju1y'19, 1915.

To all whom it may concern:

Be it known that we, OSCAR E. ERIC-KSON and HJALarAR OLsoN, citizens ofthe United States, and residents of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inCollapsible Baby-Carriages, of which thefollowing is a specification.

This invention relates. to that kind or class of vehicles which aredesigned to be folded or collapsed for shipping or storage purposes, andto be set up for use as a baby carriage.

The object of this invention is to obtain a device which, when folded orcollapsed will have the appearance of a small suit case, provided. witha handle for carrying it, which is easily set up for use asa carriage,and when set up will have a neat and sightly appearance; and which inits set up form is stable, durable, and not liable to become broken, orvget out of order.

\Ve have illustrated a device embodying this invention in the drawingsaccompany ing and forming a part hereof in which I Figure l is anelevation of the device in a collapsed or folded form. Fig. 2 is a sideelevation of the device in its set up form, for use. as a baby carriage.:Fig. 3 -is a rear elevation in the set up form, but with'the handle'and awning of the device noteX- tended. Fig. at is a planvi'ew of 'theprin cipal parts of the device'in a partially set up. condition. Fig. '5is'an end? view of the parts forming the sides of the case obtained whenthe device is'collap'sedand' the seat andiback obtained therefrom whenthe.

Patented July 4, 1916 Serial No. 40,692.

When the device is collapsed there are exposed to view, at the ends ofthe receptacle resembling a suit case, the levers D, E, and links F.Lever D forms a riser to lever E, when the device is set up, and saidlever E forms an arm rest at said time. The parts A and B are pivotallysecured together by the llnks a and pins or pivots b. Riser D isattached to part A by. pin or pivot d, lever E is attached in the sameway to part B by pin or pivot e, and levers D and E- are joined togetherby pivot or pin 6 Link F, which is pivotally attached to lever D bypivot (2 is provided with a pin orprojection G at its free end, and saidpin is movable in slot H in lever E. Pin Gr also fits in the'respectivecross slots h, h (hereinafter termed notches)-.a- Slots "H and branch or1 cross slots -h, h are hereinafter referred to as'notched slots. T

- The severallevers D, Rand-links Fwand a, are attached to the parts A,'B, and to each; other, in such manner as topermit-of the turning ofsaid parts A, :B on links-F, from a position-'whereisaid-parts are inparallel planes,--as'in-'Fig-.: 1, through an arc of approximately twohundred and seventy degrees and into-the position in which they areillustrated. in Fig. 2, so long-as the pins or abutments Gare free toslide in slots H, that is, so long as said pins'are not in one or the;otherxof'thenotchesh, 7L ,When said pins G .are in-said notches htherisers D and arms arerigidly -heldthereby, to gether with seat formedby part -A and back formed-by part "B,-in the'position in which said'partszarejillustrated in-Fig. -2-, by full lines; and when saidpin Grisin notch h said parts I are maintained in the position which" they --areindicated by broken'lin'esin said,"fipmre. r

Ifare wheel frames and.;J- a'rewheels-rotatably mounted in frames-I.Frames-I are pivotallyattached to part A by hinges K.

7c is the pintle of hinge K, and X are abutments on the part of hinge Kwhich is riveted to said part A. The abutments X are spaced so that whenthe wheel frame I is turned on hinge K, so as to be at an,

angle of ninety degrees from said part A, said wheel frame is betweensaid abutments. The wheel frames I are respectively made of strap sheetmetal which is bent to obtain two parallel sides, between which wheel Jturns, (being mounted on an axle at or near one end of said sides); saidbending being substantially as follows :--Starting at the end which islettered L, (see Fig. 3), it extends to hinge K, where it is bent aroundpintle is, to an angle of one hundred and eighty degrees, and extendsback toward the end L to a point which is a greater distance from saidend than the radius of the wheel mounted in the frame, when it is againbent to an angle of ninety degrees, to obtain the part which is letteredL it is again bent to an angle of ninety degrees to obtain part which islettered L (which is substantially parallel with the sides of theframe), and is again bent to obtain the part L and the opposite side ofthe frame. The part L is adapted to engage, or to be engaged by, the endM of riser D, when the several parts of the device are in the positionillustrated in Fig. 2, and thereby the wheel. frames I are held firmlyin their set up position, that is, at'right angles to part A.

N is a wheel frame which is pivotally attached to part A by hinges n.

O are wheels in frame N.

P is a two part lever or link. The parts of lever P are lettered 29, pand are pivotally attached together by pin 292. Part 27 of said lever ispivotally attached to part A by pin 9 and part 79 is pivotally attachedto frame N by pin 39*.

72 is a pin which limits the pivotal movement of parts 79, p on pin 79when the device is set up, (as inFigs. 2 and 3).

Q is a foot rest which consists of side bars which are longitudinallymovable in part A, the end bar 57, and the apron Referrii'ig to handleC, said handle is mounted between bars R, which are slidably mounted inpart B.

1", 1' are bends in bars R, to obtain the diagonally extending parts 1*,which extend over on to part A when the device is collapsed.

S, (see Figs. 2 and 3) arefpins or abutments on the under side of part r,'of bars R; and when the device is collapsed said abutments S areforced into apertures S of bar 1 When said pins are in said aperturesthe parts A and B are latched thereby together, so that they cannot turnon links a. Whenbars R are drawn out of the part B said pins S are drawnout of apertures S (see Fig. 2 for said apertures indicated by brokenlines in bar (j), and the parts A, B, can be turned on said links. v

T, (Fig. 2) and '1, (Fig. 3) are apertures in bars R, and U, (Fig. 3)are longitudinally movable rods which are mounted in part B, and u is aspring which yieldingly holds said rods in an advanced position. Bars Uare bent near the ends to obtain parts U which extend through slots 10in said. part B, into position to be grasped and broughttogether'against the resiliency of spring 14, thereby retracting therods U. )Vhen rods U are advanced the ends thereof are in one or theother of the apertures T, T When the device is collapsed and the handleC forced as near to the parts A, B, as possible, with the pins S inapertures S the aperture T is in position so that said. rods U may enterthem, and as said rods enter said apertures T the bars R are latched, sothat they cannot be drawn out of said part B until the ends U areforced'togethento retract said rods U from said apertures T. WVhen thedevice is set up and the handle C and bars R are drawn out the aperturesT are in position so that rods U may entersaid apertures, and

thereby latch said bars R in said position.

V, V are U-sha-ped bars, forming the frame of an awning. Bar V ispivotally attached to part B by rods U which extend through apertures insaid bars V. The sides of bar V respectively comprise an additional part(V which is-pivotally attached to the ends of bars V by pin V and saidbars V are pivotally attached. to the sides of bar V by pins V V 5 isthe textile fabric of the awning.

W is a strap which is attached to the riser D, on one side of the deviceand to the riser on the other side, to provide means for holding aninfant in the device when the same is in the condition which isillustratedin Fig. 2.

To set up the device it is held so that the pins G will not leave slot Hto enter slots it, if, and parts A, B, are turned on links a. As thedevice becomes partially set up the part A is turned so that wheelframes I will fall into position extending clownward at right angles tosaid part A, and'the completion of the set up is accomplished. As saidsetting up is completed the pins or abutments G will be in position todrop into slots h, and. link F will thenhold the several parts togetherin said set up posi- We claim 1.
